For me, personally, the Premier Membership is still worth it. While the dollar value pretty much equals what I would pay if I was doing it monthly, the convenience of a single payment is what makes it worthwhile in my circumstances. However, I do feel such a substantial price rise (about $20 this year as opposed to last year) is a little extreme. While an extra spin and access to VIP worlds and the like are nice, they would not be deciding features for or against to me. I, too, have had Premier Club since it was first introduced. I feel that those of us who have remained Premier Club members from the beginning should perhaps receive some sort of benefit similar to those pay by the month members, who are grandfathered in at $5 a month. It doesn't have to be the same price as the first year, but perhaps a discount of a certain percent for each year you buy the premier membership. For example, if this is your 2nd year of it, you get 2% off, if its the 3rd year, 3% and if you have had it from the very beginning a 5% discount. This could continue each year and incentivise players to continue a yearly membership. With most other payments, there is usually a decent saving with paying yearly rather than monthly. Jagex also gets the added benefit of receiving our money up front for the entire year, rather than having it trickle in over 12 months. Remember, also, that many players may let their memberships lapse after 6 or 7 months when they want to just take a break or don't play for a couple of months. By paying for a year up front, Jagex does not lose out if some players on the premier club quit after several months before the membership runs out.
This year seems to represent much less value than previous years, especially as the yearly fee pretty much amounts to the same as the monthly fee (at least here in Australia), but there are extra features we are receiving. Whether these extras are worth it to each individual player is something that they will have to judge for themselves. For myself, the additional 150K loyalty points is not too bad, however the rest of the bonuses I don't really care about. Even the extra TH key does not interest me. TH occasionally has something I like on it, but 1 extra key a week rarely, if ever, lets me win it.
